NA to Turbo Q's (aka What can I get away with?) - Everybodyghost - 03-20-2013

Hello everyone,

New to the site and to diesel engines in general. I've procured myself a 1980 300TD and a 1982 300D turbo, through some wheeling and dealing.

I hate to be this guy (the one hat comes on a car forum, and asks questions that have been beaten to death), but I got to be.

What I'd like to do, is keep my wagon's current engine, but go +t. Probably something low boost, as I understand that there are probably differences in compression and durability.

So the question becomes: what can I get away with? How much boost is safe, what can be reused that's already in the car, is there a preferable turbo over the stock one (Maybe water cooling?), etc.

I'm planning on an intercooler (where ever I can fit one), possibly a smaller than stock turbo for a quicker spool. What's the stock boost on a 617?

Oh yeah, and everyone loves pictures, right?

You can add a turbo, heat will kill the motor. You will need an intercooler, turbo injection pump ( or modify the NA pump), and possibly a bigger oil cooler. You should be fine so long as the EGTs stay under control.

While I'm new to diesels, I've had a few turbos in my time. Personally, I wouldn't want to run a turbo without an intercooler (At least on a gas engine, maybe the rules are different for a diesel). I was thinking I could salvage one from a Volvo 240 or 740, they're nice and big. I'd probably have to run it sideways.

I have a turbo injection pump. Are the injectors different as well? Will have to look into an oil cooler, maybe an Rx7 or Datsun cooler would work.

I was thinking that a small turbo at 7 psi would be enough to start with.

best bet...swap a turbo wagon engine

Are there differences between the wagon and sedan turbo engines?

RE: NA to Turbo Q's (aka What can I get away with?) - Simpler=Better - 03-21-2013

Wagon has a hydraulic pump in the head to run the rear suspension. Some people have swapping in the power steering/ SLS pump from newer benzes when putting a sedan engine in a wagon.

The turbo motors have a different cam, pistons, oil squirters, and sodium filled exhaust valves.

You could use a sedan turbo engine and ditch the SLS suspension and put standard coils in the rear also

I don't know, I may have the only working sls in the world. haha.

This my have all been for nothing, a friend offered me some good cash for the turbo car. Might be too good to pass up.

If it's good money take it and run. You can find turbo motors in wrecked cars typically for around $600-$800.

I'd be doubling my money, I'm running. haha

I have two wagons with working SLS one with 480,000 miles

It was hyperbole.

Well, so much for that. I'm parting the red car.
